Referring to FIG. 5, an electronic device 500 according to an embodimentof the present disclosure may have a display 501 disposed on a frontsurface thereof. In the display 501 a region in which a screen ispositioned may be defined as a display region. In the display 501, aregion other than the display region may be defined as a non-displayregion 502. For example, the non-display region 502 may be at least oneregion surrounding the display region of the display 501 on the front ofthe electronic device 500. Alternatively, the non-display region 502 maybe defined as a bezel region on front of the electronic device 500.

According to one embodiment, the non-display region 502 may be providedwith at least one button for operating the functions of the electronicdevice 500. The button is formed in a separate hole or groove formed ina glass covering the front surface of the electronic device 500 and maybe an operation button 511 that may be physically pressed. The operationbutton 511 may be, for example, a home button provided in thenon-display region 502 of the electronic device 500. The home button maybe disposed in the lower non-display region 502 of the electronic device500. When the electronic device 500 performs a specific application, thehome button 511 may move the specific application to an initial screen.Alternatively, the at least one button 512 may be a touch input button,unlike the home button 511.

The atleast one biometric sensor may be a proximity sensor 521, an illuminancesensor 522, a fingerprint sensor 531, or an iris sensor.

The proximity sensor 521may be disposed in the upper non-display region 502 of the electronicdevice 500. Alternatively, the illuminance sensor 522 may be disposed inthe upper non-display region 502 of the electronic device 500.Alternatively, the fingerprint sensor 531 may be disposed in the displayregion (screen region) of the display 501.

FIG. 6 is an exemplified diagram illustrating a front appearance of theelectronic device according to the embodiment of the present disclosure.

Referring to FIG. 6, according to another embodiment of the presentdisclosure, the front surface of the electronic device 600 may becompletely configured as a display. For example, unlike the electronicdevice 500 illustrated in FIG. 5, the electronic device 600 may have thenon-display region removed from the front surface thereof.Alternatively, the electronic device 600 according to another embodimentmay have the non-display region having a width narrower than that of theelectronic device 500 illustrated in FIG. 5.

According to the embodiment, at least a part of a display region 601 maybe provided with biometric sensors 611 and 621. For example, thebiometric sensors 611 and 621 may be a proximity sensor, an illuminancesensor, a fingerprint sensor, or an iris sensor. For example, theproximity sensor or the illuminance sensor may be disposed in a part ofan upper part of the display region 601 of the electronic device 600, asdenoted by reference numeral 611. Alternatively, the fingerprint sensormay be disposed in a part of a lower part of the display region 601 ofthe electronic device 600, as denoted by reference numeral 621.According to various embodiments, the region in which the biometricsensors 611 and 621 are disposed in the display region 601 may bedefined in advance, and address information of the predefined biometricsensors 611 and 621 may be stored in the memory.

According to various embodiments of the present disclosure, at least onebiometric sensor may be provided, and the at least one biometric sensormay be disposed in the display region 601 of the display. Therefore, thepresent disclosure may reduce a design margin of the non-display regionand may design an area of the display to be larger.

According to various embodiments, the at least one biometric sensordisposed in the display region 601 may optically recognize the biometricinformation of the user. For example, the fingerprint sensor is disposedin the first region 621 of the display region 601 of the display, andmay optically sense the fingerprint information of the user.

For example, the fingerprint sensor may include a light emitting elementand a light receiving element. The light emitting element may emit lightof a specific wavelength. If the light emitted from the light emittingelement is reflected from the user's fingerprint, the light receivingelement may recognize the fingerprint by sensing the reflected light.Hereinafter, for convenience of explanation, it is assumed that thebiometric sensor disposed in the display region 601 is the fingerprintsensor. However, in the present disclosure, the biometric sensordisposed in the display region 601 may be various in addition to thefingerprint sensor. For example, the biometric sensor disposed in thedisplay region 601 may be, for example, a proximity sensor, anillumination sensor, or an iris sensor.

In the expression described in the present document, the fact that thefingerprint sensor is embedded in the display region 601 of the displaymeans that the fingerprint sensor is embedded in pixels configuring thedisplay region 601 of the display. Alternatively, the fact that thefingerprint sensor is embedded in the display region 601 of the displaymeans that the fingerprint sensor is separately configured from pixelsconfiguring the display region 601 of the display.

If the fingerprint sensor is configured separately from pixelsconfiguring the display region 601 of the display, the fingerprintsensor may be disposed to overlap with the lower part of the pixelsconfiguring the display region 601 or may be disposed on the same layeras the pixels. For example, the fingerprint sensor may be disposed undera thin film transistor and an organic light emitting layer configuringthe pixels of the display. Alternatively, the fingerprint sensor may bedisposed under the thin film transistor and the organic light emittinglayer configuring the pixels.

Since the fingerprint sensor optically recognizes the user's biometricinformation and is also disposed in the display region 601 of thedisplay, the sensing performance may be determined according to thetransmittance of the display. The electronic device 600 according to theembodiment of the present disclosure may improve the performance of thefingerprint sensor by designing the transmittance of the region in whichthe fingerprint sensor is disposed to be relatively larger in thedisplay region 601 of the display.

According to various embodiments, the display region 601 may be dividedinto a first region in which at least one biometric sensor is disposed,and a second region other than the first region. The second region maybe a region in which the biometric sensor is not disposed. For example,a region denoted by reference numerals 611 and 621 in FIG. 6 may be afirst region as a region in which a biometric sensor is disposed.Alternatively, the region denoted by reference numeral 601 in FIG. 6 maybe the second region as the region in which the biometric sensor is notdisposed.

Hereinafter, the region denoted by reference numeral 621 in FIG. 6 isdescribed as the first region, and the region denoted by referencenumeral 601 in FIG. 6 is described as the second region.

The first region 621 may be a region for displaying an image during anormal driving period and collecting fingerprint information of a userby activating the operation of the fingerprint sensor when a specificfunction (e.g., user authentication function) is executed.Alternatively, the first region 621 may be a region that does notdisplay an image in the sleep state of the electronic device 600 butidentifies the user's fingerprint information by activating theoperation of the fingerprint sensor. According to another embodiment,the first region 621 may be a region displaying an image regardless ofwhether the fingerprint sensor is activated or not. For example, thefingerprint sensor of the present disclosure may be configured to sensethe fingerprint in a capacitive type or an ultrasonic type, in additionto an optical type. In this case, the pixels disposed in the firstregion may display an image while the fingerprint sensor senses the userfingerprint. In the above description, the technology of sensing thefingerprint by the capacitive or ultrasonic type may be the same orsimilar technology as disclosed in the prior art.

The second region 601 may be a region displaying a normal imageirrespectively of a normal driving period or an execution period of thespecific function. For example, as long as the specific function is notexecuted, the first and second regions 621 and 601 both may display thenormal image. If the specific function is executed, the first region 621does not display the normal image, but the operation of the fingerprintsensor is activated to collect fingerprint information of the user andthe second region 601 may display the normal image. Alternatively, thesecond region 601 may be a region which does not display an image in thesleep state of the electronic device 600.

The sleep state may be, for example, the locked state of the electronicdevice 600. For example, if the electronic device 600 is in the sleepstate, the low-power processor may be driven, only the operation of thefingerprint sensor or the touch sensor disposed in the first region 621may be periodically detected under the control of the low-powerprocessor, and operations of the rest devices configuring the electronicdevice 600 may stop. According to one embodiment, if the electronicdevice 600 is in the sleep state, an input of at least one button setfor the unlocking may be detected.

Hereinafter, in an electronic device according to various embodiments ofthe present disclosure, a structure and a method for designingtransmittance of a display region (first region) in which an opticalbiometric sensor (e.g., fingerprint sensor) is disposed to be relativelylarger will be described in more detail.

FIGS. 7A and 7B are plan views illustrating a pixel arrangementstructure of a first region and a second region according to anembodiment of the present disclosure. FIG. 7A illustrates the pixelarrangement structure according to the first region, and FIG. 7Billustrates the pixel arrangement structure according to the secondregion.

Referring to FIGS. 7A and 7B, the display region of the display mayinclude a plurality of first pixels 701 and second pixels 702. Theplurality of first pixels 701 and second pixels 702 may be configured todisplay a first color to a third color. Although not illustrated, theplurality of first pixels 701 and second pixels 702 may be configured todisplay a first color to a fourth color. In the above description, thefirst to third colors may be red (R), green (G), and blue (B).Alternatively, in the above description, the first to fourth colors maybe red (R), green (G), blue (B), and white (W). However, the colorshaving the plurality of pixels are not limited to the above example.

According to one embodiment, the plurality of pixels provided in thefirst region may be defined as a plurality of first pixels 701. Inaddition, a plurality of pixels provided in the second region may bedefined as a plurality of second pixels 702.

Referring to FIGS. 7A and 7B, in the display according to theembodiment, the arrangement forms of the pixels 701 and 702 provided ineach of the first and second regions may be different from each other.For example, the form in which the plurality of first pixels 701 arearranged and the form in which the plurality of second pixels 702 arearranged may be different from each other. For example, the plurality offirst pixels 701 are arranged in a matrix form and the plurality ofsecond pixels 702 are arranged may be in a zigzag form. For example, inthe plurality of first pixels 701, a red color pixel (R), a green colorpixel (G), and a blue color pixel (B) may be arranged in a straight formin a first direction (e.g., horizontal direction 711) and a seconddirection (e.g., vertical direction 712). Alternatively, in theplurality of first pixels 701, an R, a G, and a B may be arranged in azigzag form in a first direction (e.g., horizontal direction 721) and asecond direction (e.g., vertical direction 722).

In the electronic device 600 according to the embodiment, an interval d2between the plurality of second pixels 702 is formed to be narrower thanan interval d1 between the plurality of first pixels 701, such that thetransmittance of the first region may be higher than that of the secondregion. For example, the maximum spacing distance d1 between firstpixels 701 to each other in the first region may be larger than themaximum spacing distance d2 between second pixels 702 adjacent to eachother in the second region. The maximum spacing distance between pixelsadjacent to each other may mean the largest value among distancesbetween a specific pixel and pixels adjacent to each other to thespecific pixel.

As illustrated, in the electronic device according to an embodiment ofthe present disclosure, the form in which the pixels are arranged in thefirst region differs form the form in which the pixels are arranged inthe second region, and the maximum spacing distance between pixelsadjacent to each other is relatively larger in the first region.Accordingly, the transmittance of the first region is relativelyincreased, and therefore the performance of the fingerprint sensor maybe improved.

FIGS. 8A and 8B are plan views illustrating a pixel arrangementstructure of a first region and a second region according to anotherembodiment of the present disclosure. FIG. 8A illustrates the pixelarrangement structure according to the first region, and FIG. 8Billustrates the pixel arrangement structure according to the secondregion.

The plurality of first pixels 801 a, 801b, and 801 c, and second pixels 802 a, 802 b, and 802 c may beconfigured to display a first color to a third color. Although notillustrated, the plurality of first pixels 801 a, 801 b, and 801 c, andsecond pixels 802 a, 802 b, and 802 c may be configured to display afirst color to a fourth color. In the above description, the first tothird colors may be red (R), green (G), and blue (B). Alternatively, inthe above description, the first to fourth colors may be red (R), green(G), blue (B), and white (W). However, the colors having the pluralityof pixels are not limited to the above example.

According to the embodiment, the plurality of pixels provided in thefirst region may be defined as a plurality of first pixels 801 a, 801 b,and 801 c. In addition, a plurality of pixels provided in the secondregion may be defined as a plurality of second pixels 802 a, 802 b, and802 c. The plurality of first pixels 801 a, 801 b and 801 c may includea pixel 801 a displaying a red color, a pixel 801 b displaying a greencolor, and a pixel 801 c displaying a blue color. The plurality ofsecond pixels 802 a, 802 b and 802 c may include a pixel 802 adisplaying a red color, a pixel 801 b displaying a green color, and apixel 802 c displaying a blue color.

Unlike the example illustrated in FIGS. 7A and 7B, in the exampleillustrated in FIGS. 8A and 8B, the arrangement forms of the pluralityof pixels provided in the first and second regions may be the same.However, the plurality of first pixels 801 a, 801 b, and 801 c may befewer in number than the plurality of second pixels 802 a, 802 b, and802 c, or may have resolution lower than that of the plurality of secondpixels 802 a, 802 b, and 802 c.

For example, as illustrated, the plurality of first pixels 801 a, 801 b,and 801 c and the plurality of second pixels 802 a, 802 b, and 802 chave the same arrangement shape, but some regions of the first pixels801 a, 801 b, and 801 c may not be formed with pixels. For example, atleast some region 810 of the plurality of first pixels 801 a, 801 b, and801 c is a region in which the pixel 801 b displaying a specific color,for example, a green color needs to be formed according to anarrangement rule, but the corresponding region 810 may not be formedwith pixels. Alternatively, at least some region 810 of the plurality offirst pixels 801 a, 801 b, and 801 c is a region which the pixel 810 bdisplaying a green color needs to be formed while matching the pixel 801b displaying a green color that is provided in the second region, butthe corresponding region 810 may be open without being formed withpixels.

In the electronic device 600 according to the embodiment, a part of apixel representing a particular color in the first region may be deletedand the deleted region may be open. Therefore, the electronic device 600according to the embodiment can increase the transmittance of the firstregion and improve the performance of the fingerprint sensor. In theelectronic device 600 according to another embodiment, a transmitter(e.g., ultrasonic oscillator, infra-red light emitting diode (IRLED), orthe like) or a receiver (e.g., ultrasonic receiver or IRLED receiver)for biometric recognition may be included in the deleted region.

The electronic device 600 according to another embodiment may increasethe transmittance of the first region without making a design to deletepixels in a specific region beyond the pixel arrangement rule. Forexample, the plurality of first specific pixels 801 a, 801 b, and 801 camong the plurality of first pixels 801 a, 801 b, and 801 c and theplurality of second pixels 802 a, 802 b, and 802 c are arranged in thesame form, but the interval between pixels adjacent to each other can beincreased by reducing areas of each pixel. Therefore, the areas of eachof the first pixel may be smaller than those of each of the secondpixels.

FIGS. 9A and 9B are plan views illustrating a pixel circuit structure ofa first region and a second region according to an embodiment of thepresent disclosure. FIG. 9A illustrates the pixel circuit structureaccording to the first region, and FIG. 9B illustrates the pixel circuitstructure according to the second region.

Referring to FIG. 9A and 9B, in the electronic device 600 according tothe embodiment, the circuit structures of the pixels configuring thefirst region and the second region of the display may be different fromeach other. The display may be configured as an OLED display. Asillustrated, the OLED display may be configured so that each pixelincludes at least one switching element (e.g., thin film transistor), atleast one capacitor, and at least one OLED.

According to one embodiment, the pixels of the first region may includea smaller number of elements than the pixels of the second region. Anelement configuring each pixel, for example, a thin film transistor or acapacitor may be made of an opaque metal. Therefore, if the number ofelements configuring each pixel is increased, the transmittance of thepixel may be reduced. In the electronic device 600 according to theembodiment, each pixel included in the first region is configured toinclude a smaller number of elements than each pixel included in thesecond region, thereby increasing the transmittance of the first region.For example, each of the first pixels may include a (a is an integergreater than or equal to 2) switching elements and b (b is an integergreater than or equal to 1) capacitors, and each of the second pixelsmay include c (c is an integer greater than or equal to a) switchingelements and d (d is an integer greater than or equal to b) capacitors.

For example, referring to FIG. 8A, each of the first pixels may includetwo thin film transistors T1 and T2, one capacitor Cstg, and an OLED.Since the pixel structure of the OLED display illustrated in FIG. 8A isa basic pixel structure widely known to those skilled in the art, adetailed driving method thereof will be omitted. In addition, referringto FIG. 8B, each of the second pixels may include seven thin filmtransistors TR1 to TR7, one capacitor CST, and an OLED. The pixelstructure of the OLED display illustrated in FIG. 8B is for improvingthe process variation of the thin film transistors TR1 to TR7 and thereaction speed of the pixels, and may be variously changed. However,since the pixel structure of the OLED display illustrated in FIG. 8B isdisclosed in Korean Patent Laid-Open No. 10-2016-0024191, a detaileddriving method thereof will be omitted. The pixel structure of thepresent disclosure is not limited to the example of FIGS. 8A and 8B andmay be variously modified or changed.

FIG. 10 is a diagram schematically illustrating a cross-sectionalstructure of a first region according to an embodiment of the presentdisclosure.

Referring to FIG. 10, the first region of the display may besequentially laminated with a thin film transistor 1001 and an OLED1002. The thin film transistor 1001 and the OLED 1002 may be connectedto each other through a transparent electrode 1003. The thin filmtransistor 1001 may be any one of the plurality of thin film transistorsillustrated in FIGS. 9A and 9B, for example, a driving thin filmtransistor T1 illustrated in FIGS. 9A and 9B.

Referring to FIG. 11, at least some of the components of the fingerprintsensor may be formed on the same layer as the first layer L1 or thesecond layer L2. For example, the light emitting element 1110 may beconfigured as an organic light emitting element on the second layer L2.At least some of the organic light emitting elements configuring thelight emitting element 1110 may be configured to emit invisible light.The invisible light may mean, for example, light having a wavelengthband other than light in a visible region. For example, the invisiblelight may be light in the infrared region or light in the ultravioletregion. According to one embodiment, the light emitting element mayoutput light having a specific wavelength, for example, green light. Inaddition, a light receiving element 1120 may be disposed under thesecond layer L2, like the light receiving element 1020 illustrated inFIG. 10.

According to the embodiment, in the first region, at least one of thefirst and second layers L1 and L2 may be provided with a light shieldingbarrier 1130. The light shielding barrier 1130 may prevent light outputfrom the light emitting element 1110 from being introduced into a thinfilm transistor 1101 due to the reflection. The light shielding barrier1130 may be made of resin or metal capable of absorbing or reflectinglight.

According to the embodiment, the second layer L2 may be provided with alight shielding filter 1140 that transmits only light having a specificwavelength. For example, the light shielding filter 1140 may transmitonly the light having the wavelength band output from the light emittingelement 1110. For example, if the light emitting element 1110 outputsgreen light, the light shielding filter 1140 may transmit green lightand cut off light having another color or another wavelength band.According to one embodiment, the light shielding filter 1140 may bedisposed to overlap with the light receiving element 1120. The lightshielding filter 1140 may serve to filter remaining light so that onlythe light output from the light emitting element 1110 and reflected maybe supplied to the light receiving element 1120.

FIG. 12 is a modified example of the cross-sectional structure of thefirst region according to another embodiment of the present disclosure.

Referring to FIG. 12, in the electronic device according to anotherembodiment, the light receiving element 1220 may be formed on the samelayer as the thin film transistor 1201, unlike the electronic deviceillustrated in FIG. 11.

Referring to FIG. 13, in the electronic device according to variousembodiments, a light receiving element 1320 may be formed on the samelayer as the OLED, unlike the electronic device illustrated in FIG. 11.For example, the light receiving element 1320 may be formed on thesecond layer L2 on which the OLED and a light emitting element 1310 areformed. The light receiving element 1320 may be configured as an organicdiode which is switched in response to light having a specificwavelength. A light shielding barrier 1330 may be formed on the secondlayer L2 between the light receiving element 1320 and the thin filmtransistor 1301.

FIG. 14 is a diagram illustrating a pixel arrangement structure of afirst region and a second region according to an embodiment of thepresent disclosure. For example, FIG. 14 may be an enlarged view of atleast a part of a first region 1410 of an electronic device 1400 and atleast a part of a second region 1420 of the electronic device 1400.

In FIG. 14, reference numerals 1410 a, 1410 b, 1410 c, 1420 a, 1420 b,and 1420 c may indicate the shape and area of the light emitting region(display region) of the corresponding pixel.

Referring to FIG. 14, the display region of the display may include aplurality of pixels. The plurality of pixels may be configured todisplay a first color to a third color or a first color to a fourthcolor. Although not illustrated, the plurality of pixels may beconfigured to display the first color to the fourth color. In the abovedescription, the first to third colors may be red (R), green (G), andblue (B). Alternatively, in the above description, the first to fourthcolors may be red (R), green (G), blue (B), and white (W). In thepresent disclosure, the colors having the plurality of pixels are notlimited to the above example.

According to one embodiment, a plurality of pixels 1410 a, 1410 b, and1410 c provided in the first region 1410 may be defined as a pluralityof first pixels 1420 a, 1420 b, and 1420 c. In addition, a plurality ofpixels provided in the second region may be defined as a plurality ofsecond pixels 1420 a, 1420 b, and 1420 c.

Referring to FIGS. 7A and 7B, in the display according to theembodiment, the arrangement forms of the pixels 1420 and 702 provided ineach of the first and second regions may be different from each other.For example, the shapes of the plurality of first pixels 1410 a, 1410 b,and 1410 c and the shapes of the plurality of second pixels 1420 a, 1420b, and 1420 c may be different from each other.

In the above description, the fact that the shapes of the pixels may bedifferent may mean that the shapes of the light emitting regions(display regions) of the respective pixels arranged in the respectiveregions (first region 1410 or second region 1420) are different. Forexample, as illustrated in FIG. 14, the first pixels 1410 a, 1410 b, and1410 c disposed in the first region 1410 include a light emitting regionhaving a rectangular shape, and the second pixels 1420 a, 1420 b, and1420 c disposed in the second region 1420 may include a light emittingregion having a triangular shape.

Alternatively, in the above description, the fact that the shapes of thepixels are different may mean that the areas of the light emittingregions of the pixels displaying the same color in each region (firstregion 1410 or second region 1420) are different. For example, asillustrated in FIG. 14, the first pixel 1410 a displaying a red (R)color among the first pixels 1410 a, 1410 b, and 1410 c disposed in thefirst region 1410 is configured to include the light emitting regionhaving the first area, whereas the second pixel 1420 a displaying a redcolor among the second pixels 1420 a, 1420 b, and 1420 c disposed in thesecond region 1420 is configured to include the light emitting regionhaving the second area different from the first area.

Alternatively, in the above description, the fact that the shapes of thepixels are different may mean that the arrangement order between thepixels displaying different colors arranged in each region (first region1410 or second region 1420) is different. For example, as illustrated inFIG. 14, in the first pixels 1410 a, 1410 b, and 1410 c disposed in thefirst region 1410, a 3k−2 (k is an integer)-th column (e.g., firstcolumn) may be formed with a red pixel 1410 a, a 3k−1 (e.g., secondcolumn)-th column may be formed with a green pixel 1410 b, and a 3k-thcolumn (e.g., third column) may be formed with a blue pixel 1410 c. Onthe other hand, odd columns of the second pixels 1420 a, 1420 b, and1420 c disposed in the second region 1420 may be alternately formed withred and blue pixels 1420 a and 1420 c and even columns thereof may beformed with a green pixel 1420 b.

Alternatively, in the above description, the fact that the shapes of thepixels are different may mean that the arrangement form of the pixelsdisplaying the same color arranged in each region (first region 1410 orsecond region 1420) is different. For example, as illustrated in FIG.14, in the first pixels 1410 a, 1410 b, and 1410 c disposed in the firstregion 1410 the pixels having the same color may have the samearrangement form regardless of colors. For example, all of the secondpixels 1420 a having the red color among the second pixels 1420 a, 1420b, and 1420 c disposed in the second region 1410 are arranged in thesame shape. On the other hand, the first pixels 1410 a disposed in thefirst region 1410 may have different arrangement forms even if they arepixels of the same color. For example, the first pixels 1410 a havingthe red color disposed in the first region 1410 may be arranged in aninverse triangle shape in an odd row, and may be arranged in a triangleshape in an even row so that they have a shape symmetrical to those inan odd row.

FIG. 15 is a flow chart of an operation of a display driver according tovarious embodiments of the present disclosure.

Referring to FIG. 15, a flow diagram of an operation of a mapping moduleconfigured in a display.

In operation 1501, the display driver 450 may receive a display data,i.e., an image data, from the AP or the LPP.

In operation 1503 and operation 1505, the display driver 450 matches thereceived image data for each region based on the positional informationcorresponding to the first region 442 and the second region 444 of thedisplay, and may determine the image data as the first data or thesecond data based on the matched result. For example, the display driver450 may determine, as a first data, data to be supplied to the firstregion 442 among the received image data, based on the positionalinformation of the first region 442. Alternatively, the display driver450 may determine, as a second data, data to be supplied to the secondregion 444 among the received image data, based on the positionalinformation of the second region 444.

In operation 1507 and operation 1509, the display driver 450 may convertthe determined first and second data according to the structure anddriving characteristics of the corresponding region. As described above,according to various embodiments of the present disclosure, at least apart of the structure, form, shape, or arrangement structure of thepixels configuring the first region 442 and the second region 444 may beconfigured differently. Therefore, even if the same image data isapplied, the first pixel arranged in the first region 442 and the secondpixel arranged in the second region 444 may output light havingdifferent gradations, which may cause a luminance deviation and an imagequality defect. Therefore, the display driver 450 of the presentdisclosure may perform image processing on the first data supplied tothe first region 442 and the second data supplied to the second region444 in order to prevent defects such as the luminance deviation.

For example, the display driver 450 may convert the first and seconddata based on the size of the first area of the light emitting region(display region) of the first pixel and the size of the second area ofthe light emitting region (display region) of the second pixel disposedin the second region 444. For example, the display driver 450 maygenerate the first converted data by giving a high weight to the firstdata because the light emitting region of the first pixel may have arelatively smaller area. Alternatively, the display driver 450 maygenerate the second converted data by giving a low weight to the seconddata because the light emitting region of the second pixel may have arelatively larger area. Various embodiments of the present disclosuremay prevent the image quality defects such as the luminance deviation byconverting the image data supplied to the corresponding region based onthe structure and driving characteristics between the pixels disposed inthe first and second regions 444.

Alternatively, the display driver 450 may convert the first and seconddata based on a first resolution of the first pixels configuring thefirst region 442 and a second resolution of the second pixelsconfiguring the second region 444. For example, the display driver 450may generate the first converted data by giving a high weight to thefirst data because the resolution of the first region 442 may berelatively low. Alternatively, the display driver 450 may generate thesecond converted data by giving a low weight to the second data becausethe resolution of the second region 444 may be relatively high.

In operation 1511, the display driver 450 may output the converted firstand second data to a source driver.

FIG. 16 is a flow chart of an operation of an electronic deviceaccording to various embodiments of the present disclosure.

In operation 1601, the processor 430 may detect the user input. Forexample, the processor 430 may control the display to display the userinterface requesting fingerprint authentication. For example, theprocessor 430 may execute a specific application and if the userauthentication is required, request the fingerprint input to the userand provide the user interface describing the fingerprint input method.The processor 430 may receive a signal corresponding to the fingerprintinput from the user through the user interface.

In operation 1603, if the user input is the fingerprint detectionrequest, the processor 430 controls the display driving circuit to drivethe pixels of the first region 442 in which the fingerprint sensor isformed or may drive an external light source to output light. Forexample, the processor 430 may determine whether the user input is thefingerprint input. The processor 430 may output light to the firstregion 442 for the fingerprint sensing if the received user input is thefingerprint detection request, that is, the user receives the signalgenerated by inputting a fingerprint to the first region 442. Forexample, the processor 430 may control the display driving circuit tooutput light through the pixel corresponding to the first region 442.Alternatively, the processor 430 may output an infrared light bycontrolling a light source device that is separate from the display, forexample, a light source device that outputs infrared light. The lightoutput through the first region 442 of the display or the light emittedfrom the light source device may be reflected from the user'sfingerprint and supplied to the light receiver of the fingerprintsensor.

In operation 1605 and operation 1607, the processor 430 may sense thelight reflected from the user's fingerprint by the fingerprint sensor,and perform the set function based on the fingerprint sensing result.For example, the processor 430 may transmit information obtained fromthe fingerprint sensor to the processing module, the AP, and the LLP,and may receive an instruction word from the processing module, the AP,and the LLP to perform the functions according to the fingerprintsensing result.
